Hi Dear All,

The original topic of my post is 'Prostate cancer with bone metastasis' ...I had started my dad on the Budwig diet about 3 weeks ago...he started losing weight...but was eating and drinking well...until a few days ago he started having difficulty swallowing liquids...I attributed it to his Parkinson's and increased his dose of medicine for it...it seemed a little better for a coupel of days then since yesterday eh has been having great difficulty and has been holding water in his mouth for more than a min or so ...so much so I was not able to give him his 8 glasses of water /day just 2-3......yesterday most of the day he has been sleeping and was arousble with difficulty, he was tilted to one side but still eating well..when awake...since dinner time last night eh is not waking up and snoring very heavily...I am suspecting he might have had a stroke.. though there are no frank signs...( I am a physician but do not practice as I have been and want to take care of my dad )except the swallowing problem which could be from Parkinso's -he is moving all his limbs and body parts etc but not able to get up from his sleep...I had to skip dinner...I just tried to wake him up and told him I will get his breakfast and he opened his eyes and said yes then fell asleep........and snoring.....what could be the reason ??? I do not want to take him to the hospital...
Just gave him one sip of Arnica 30c water...should I do the plussing...or just give it to him normally..?

Please advice !!!

Million thanks and kindest regards
